OOMBINATION' STOP ACTION FOR ORGANS.

The invention relates t combination st0p actions -f01 organs. 1

In c0mbination st0p actions contro1led from the console 1'01 bothsetcing and bringfing 0n the various combinations, the mechanism hasheretof0le been of such constructi0n 215 t0 necassitate its dispositionwithin the console, which has limited the number 0f combinatiensthaccould be provid ed be- 1o cause of the relatively small spaceavailable, and'has 1ed so difliculties when repairs 0r adjustmentsbecmne necessary begrause of inaccessibility of parts.

An object of the present invention is to provide an electri0allycontrolled mechanism f01 simultaneously 1noving a predeterminedarrangement 0f organ stops t0 either operative 01 inoperative position,and also to permit independent actuation of any organ stop within 0 3With0ut the desired group W1thout changing the group arrangement,Whereby the mechanism c an be disposed at any suitable location distantfrom the console and thereby capable 0f incorporating any desired number0f combinations and permitting flexibility in installation; it beingthen possible t0 manufacture consoles in standard sizes reg'aldless 0I"the number 0'f combinations incorporated and to readily install the 3hmechanism in existing organs.

Another object of the invention is t0 provide a combination stop actionmechanism including movable members carrying tw0- position switches 01 anove1 design f01 c0ntrolling circuits admiting sops t0 a combination 01exclucling them therefrom and means f01 s?multaneously setting aplurality 0ft sWitches to either of their desired positions.

A further objecs of the invention is 00 provide a coznbination stopaction in which swiiches 011 the console unde1 the control 0f theorganist serve both to bring 011 combinations 211d t0 setcombinations,an additio'nal common control switch being used in conjunction forperforming t-he 1atter opera ti0n A further objec of the invention is toperiect details of conscruction generally to provide for simplicity andcompactness.

The invention further consists in the sev e1a1 u?eatures hereinafter setforth andmore particularly defined by claims atthe conclusion hereof.

As is wel1 known, a pipe Organ ii1cludes a number 0f stops and mez;nsf0r inde.pendent1y operating the same. The organ stops have noc beensh0wn in the drawi1igs, as they are 0f usual canstruc tion, such as thefaken electropneumatically controlled tjrpe. Stop operating devices inthe console may be 01 any type, but in the dmwings are shown t0 be stopkeys 10 vvh1ch a1e p1vota'lly mounted fo1 111dependent rockmgmovement011 the stationary horizontal shaft 11 in the usual manner, splings 12serving to retain the stop keys 111 -the1r off and 0n positionS and thestop keys be1ng so arranged -that they are Co be depressed in order t0bring them to thei1" an po'siion. In the latt,er position, a bridgingcontact pin 13 on the stop key engages a pair 01 relativlystationaryspring contact members 14 to establish a circuit rendering effective thecorresponding st0p. This circuitincludes a battery 15, 01 othe1si1itable source of current, a C011- ductor 16 connecting the' batteryWith one of the stationary contact members 14 associaterl with each stopkey, and a conductor 17 connected t0 the othey 0f the stationary contactmembers and leadingto the immediate controlling mechanism .of the corresponding st0p.

In the present instance, the st op keys 31e' uailized as a common meansfor con tfolling the stops either manually 01 throughthe functioxrlng ofa combination-efiecting mechanism hereinafter describec]. Bach stop keycar:cies at its rear end within the fron't Wall cf the console 18 a,vertic-ally extending f electro-pneumatic clevices common in organconstruction, so that when either 01 the electromagnets 1s energ1zeclthe stop key Wlll be movecl t0 1ts respec-ve off am].

The mechanism for ehe procluction 0f various combinations is placecldistant from the console in anyconvenient location near 017 within theorgan space ancl includes movable trace bars 24, there being 0ne foreach stop ancl each carrying a plurality 01 switch elements equal innumber to as many combinat-ions as are desired. Tl1e t1ace bars a1epreferably disposecl horizontally ancl are slidably 1nountecl 011transversely extending supports 26 ancl 27 secured to longitudinallyextencling housing members 28 with which they vforrn a trace barsupporting f1ame. Strips 29 extencling transversely above the trace barsare securecl at their ends to the housing members 28 ancl carryclepending pins 30 which serve 130 space und guicle the trace bars. Thetrace bars each carry a depending stop pin31engageable Wih a stop 32 andthe forwa1:cl support 27 in its respec- -131V8 extreme pos1tions. Eachtrace bar is moved t0 ancl retainecl in its normal 1earward pjos1t1on bymeans 0f a V-spr1ng 33 hav1ng' one encl chsposecl in'an opemng 34 1n therear support 26 ancl the other encl hooked in a screw-eye 35 depenclingfi0fl1 the rear end of the bar. A slotted strip 36 securecl against therear face 0f the support 26 serves t0 maintain the springs in theirvertical parallel osition.

'Th switch elements 25 on each trace bar serve to control the off anclon positions 0f the st0p keys through circuits hereinafter describeclalternatively energizing the st0p u key control magnets 22 and 23. Eachswitch upper edge 0f the trace bar.

element comprises a movable switch 1nembei 37 formed ofsheet metal andpivoted to 10ck in a vertical plane on a screw 38 01' other suitablefastening cleVice disposed near the F01 th1s purpose t-he switch memberis provicled with downwardly extencling spacecl tongues 39 which form afork 110 be slippecl over the screw behind its heacl. The sw'1tch memberis then retained 011 this screw by means of rounded projections 40struck up 0n each tongue' 39. The uppereclfge 0f the switch member isdisposed adjacent the upper edge of the trace bar and is formedtopresent upwardly extencling projections 41 on either sicle 0f pivotfork, so that one 017 the other of these projections may extencl abovethe upper edge of the trace bar in position to be moved downwardly toeffect a rocking o1 oscillatory movement 0f ehe switch member. Theswitch member is provicled .with depencling arcuate contact fingers 42ab its sides which are aclaptecl to engage one of a pair of contacts 43and 44, which extend through the trace bar to form wiring terminals 0nthe opposite sicle, as does the screw 38. The contacts 43 on any onetrace rod a1 e all connectecl together and the contacts 44 arelikewiseconnected, so that there are two sets of contacts, the contacts in eachset being connectecl in parallel. The contacts 43 and 44 arerespec'tively connectecl by conductors 45 anal 46 to the stop keycontrol magnets 22 ancl 23 in tl1e console, while the screws 38 in anyone trace bar a1e connected by individual conductors 47", 47", 47, etc.,to the contact springs 48 of elecbro-pneumatically c0ntrolledcombination relays 49", 49" and 49, etc., there being one 0:E theserelays 'f0r each combination t0 be efiected by the mechanism. There areas manycontact springs 48 in each relay as there are trace bars, with anadditional one or two f01 receiving a current supply conductor 50, whichleacls t0 the battery 15. The contact springe. 48 in each relay ai-econnected. to ehe laterally acljacent switch members 0f the severaltrace bars, sinne one transversely extending I'OW 0f switch members 0nthe several trace bars is present f01' each combination. The combinationrelays 49", 49", 49, etc., each 'include a bellows 51 which carries abridging contact 52 f0r simultaneously establishing a C011- necztionbeween the supply concluctor ancl the several conductors 47'", 47" and47", the operation 01 each being controlled by an electromagnet 53. A5.these relays are 0f well known construction, they are only illustrateclschematically in the drawings.

The wiring 0 11 the trace bars is shown in detail in Figs. 5 t0 7wherein ehe several comductors ar6 connectecl to the screws 38 and thecontacts 43 und 44 by solclering them to the projecting parts 0f thesemelnbers on the sicle 0f tl1e trace bar opposite tl1e switch membei-s37. The 1ear ortion of tl1e trace bar is proviclecl with alongitudinally extending dove-tail sl0t 54 t0 receiwe the Gable formedby the several conductors, which are helcl therein ancl 011- the side ofthe bar by tied cords 55 passing through openihgs 56 in the bar.

rent from the battery 15 by a concluctor 57,

ancl the other si le3 0f the magnets a1e C011- nected by inchviclualconductors 58", 58", 58,

etc.,*to normlly closed -setsof cohtacts 59, 60, o-f arelay hereinafterdescribed. The contacts 59 are connected by conductors 61, 61", 61,etc., 130 respective contacts62 in combination push button switches 63,63, 63, etc.,-which are mounted in the console for operation by theorganist. Contncts 64 in each switch are connected t0 the proper side ofthe battery 'by a conductor 65. The switches also include contacts 66and 67, the 1atter 0ne being ofi'set back frorn the sontacts 62, 64 and66 in orderto be engaged by a b'ridging contactmember 68 after it hasengaged the other contacts. The bridging contact nlember 68is mounted011 each of the springretractedpush buttons 01 pistons 63, which areidentified by numbers in the usual manner.

There is a push button f0r each combination*and each serves as theimmediate coutrol for 0ne of the cornbination relays 49, 49, 49, etc.VVhen the c0mbination push button 63 is'pressed, it establishes acircuit from thebattery 15 through conductor t0 contact 64, throughbridging member 68 t0 cont-act62, through conductor 61 t0 the normallyclosed contacts 59, 60, through con ductor 58 to the electromagnet 53 0fthe re1ay 49 and back to the other side of the battery through conductor57. This serves to operate the re1ay 49, which then estabh'shes a ircuitfrom the battery 15, through the conductor 50, the bridging cont-act 52on the relay, the contact springe; 48, and from thence t0 the series ofconductors 47 connected to a transversely extendi ng 1OW f switchmembers 37 0n the seveml trace bars 24 in order t0 control all he stopkeys inthe group in which thecombination is t0 be effected. When theswitch memhers 37 rest on the 01T contact-s 43, current then flowsthrough conductor 45 t0e1ectromagnet 22 andifr0m thence 110 the batterythrough conductor 69. If a stopkey was previously in the 011 position,it is moved 'by' the bellows 20 to off position in accordance with theposition of the switch member 25 on the trace bar, While if it isalready in off position, its condition -is not disturbed. F or thosestop keys which are desired t0 be'brought to the 0n position in order t0include them in a desired combination, selected switches on thecorresponding trace bars have been previously moved 130 on position bymeans of setting delvices hereinafter described, so that when thecombination push button is pressed it Will operate the combination relay49, Which Will direct a current through the last-named switches t0 theon position electromagnets 23. Since the combinat-ion relay 49 Will0111y direct current through one transversely extending row of switchmem'bers 37 011 the trace bare, it Will be apparent that the position ofthe remaining switch members on the several trace bars=willhave 110efi'ect in bringingon the des1-red combmat1on, butaro onlyefi"ectivewvhen -they occur 111 the row 0f sWitch men1bers throughwvhich a circuit Will be establishecl byhe operation ofthe correspondingcombination relay. TIt Will also be noted ahnt n0 movemcntof the trz1cebars occurs whencon1binations are brought As is we11 understood in thisart, the trace bars are moVed t0 a setting position eit=herpneumatically 0r electrically, und in the presenfi instance I' haveaccomplished this operation electrically. Ahook bar 70is pivoted t0 theforward end ofeach trace bar by a screw 71 and is movablejn .a vert-ic11plane fromm a substantially horizontal position. The forward end of thehook bar has an upwardly extnding p1oj ecion 72and a counter weight 73is-provided at. therear Which partially Offsets the weight. atz thefront portion, in Order that the hook bar may be mised With very litfleeffort. The hook bars are guided in VertiCal slots 74 in the upper part0f a transversely *extending frame member 75 ab the forward en l 0f t-heframe, and are limited in their upward movement by a covering strip 76,which closes the upper openings of the s1'ots. Ab their forwardporc-i0ns the hook bare; 70 rest at a suitable elevation 0n theupperedge of strip 77, secured to the forward face of the frame member 75 byscrews 78 Which pass through s1ots 79 in the stript0 permit up-and-downadjustinent. When the' hook bars :are ]ifted they reak;h a position t0be engaged by 21 bar 80 carried by arms 81 which have their lower endssecured 130 a roclvshaft 82journalled in the housing menrbers 28. Theswinging bar 80 is provided-wvi'th a='strip 0f raw-hicle 83 0r othersuitable material at the edge where it engages the hook bars in ord'ert0 deaden sound and insure longwear. The r0ck-shaft 82 carrieszr lever84, which is operatively connected to the core 85 0fnsolenoid 86, and isbald in its normally inactive osition by a spring 87. The solenoid isconnected t0 the battery 15 hy condutztors 88 and 89 through a normallyopen set Cf contacts 90 included in conductor 89 and disposed 0n a re1ay91 which is controlled Joy circuits hereinafter described. -The closingof the relay contacts serves; t0 energize the solenoid, which rriovesitscore t0 produce a movement 0f the swinging bar 80 und with it theforward 1novement of any one of the trace bare. whose hook bar 70 i'S inposition t0 be engaged by the bar. 4

The movement 0f euch hook bar 70 t0 uctuating position is produced by-an e1ectromagnet 92 having its core endsmounted in t-he non-magneticcovering strip 7 6above the hook bar, which is 0f iron t0* f0rm anarmature. Bach electromagnet- 92 is' c0nnected Eo 011e side ofthebatteryby conductor 93 ancl has the other encl of its Winding connected by a conductor 94 leacling c0 the c0nductor 17, tl1e latterconclnctor joining the stop key switch ancl the stop action proper. ASet 0f normally open eoniacas 95, being inelndecl in conductor 94, areincorporaaed in a relay 96 Whiel1 also inclucles the contacts 59, 60,the latter being inclucled in the immediate cireuits f0r the combinationpush butto1ns. The hook bar lifting magnet 92, being c0nnectecl inparallel Wibli t11e cirenit operating tl1e stop action, is controlleclby the stop key when the relay eontac1s 95 am closed as hereinaffer set'101'bh.

As previously statecl the switch me1nbers 37 0n the trace bars are1novable to an 01 011 positions by means of parts of their upper eclgesp10j eeting above ehe npper eclge 01' the trace bar. A switeh aetuat0r97 er;- tends transversely above the trace bars in p0sition 130simultaneously roch a transversely extending 1OW 0f swii'ch members Whenit is movecl downware.l1y against the upper eclge 0f the trace bare.There is one actuator f0r each transversely (3X13111111g row 0f switchmembers, and acc0fllingly 101 eacl1 combination. The actualor isvertieally movable 011 g1lide pins 98 anal 99 secured int0 the upperedge of the housing men1bers 28 011 either side 01' the group of tracebar-s and is retaiilecl in its normal upper position by a spring 100surrouncling the guidepin 98 and haVing its lower, encl clisposecl in arecess 101 in the housing men1ber 28. The upper encl of the pin 98 isproviclecl with nuts 102 which retain a cnshion-washer 103 101 limitingtlie upward movement of the switch actalor.

The pin 99 guides the other sicle 01 the switch actuator by passingthrough a slot 104 1herein.

Rockshaft 114 carries alever 115 whichis operatively connectecl to the eore 116 of the selenoid 117, the lever115 being held in it-s normal inactive position by spring 118., Thesolenoid 117 is conneeted 130 the battery by concluctors 119 ancl 120through a normally open SG1J 01 contacts 121 included in conduc- 1101120 and clisposecl 011 a relay 122, which is controlled by circuitshereinafter de- .scribecl. The closing 0f the relay contactsserves toenergize the solenoid, which moves its c0re to procluce a movement ofthe-swinging bar 112 and with it the movement 0f one 01 the links 109whose hook bar 111 is in position 110 be engaged by the swinging bar112.

Tl1e 1n0vement 01: each hook bar. 111 to aetuating position isproclucecl by an eledtro- 1nagnet 123 haVing its core ends mounted in anon-magnetic strip 124 above the hook bar,

which is o1 ir0-n t0 ;f0rm an. armature. Each electromagnet 123 isconnectecl to one sich: 01 the battery by concluctor 125 and has theother end 01 its winding connected b a c011cluetor 126 t0 a contact 1270n the re1ay 96.

A combination control push button 128 is monntecl in the console for0p(3121131011 by the organist anc1 is used in conjunction with thecombination push buttons when it is clesi1ed to set co1nbinaci0nS. Thecon'nbination control pusl1 button ineludes: contacts 1.29

The relay 96 inclucles thenormally closecl contacts 59, 60, and t11e normally open sets ofcontaets 95, 134 and135. The contact 127 is adapted to co-operateW1111C011121C0 59 wl1en the relay is aetuated. The movable contxcts 01the iela'y. are lnountecl 0n a movable 1nembe'r 136 actuate'd by abellows 137. 011 this relay there is one set of concaets 59, 60, 127,for euch combination, one sei; of contacts 95 i:'0r each stop key anclone sei; 0'f contacts 134 and 135. The eontacts 66 0n alle combinationpush buttons a1e eonnectecl by a common conducc0r 138 to one o tl1e pair0f contaets 134, the other of these latter contact-s beim; c0nnectecl bya concluctor 139 with the winding 01 the relay 91, which l1as aconnect-ion to the battery 15 l0y a c0nductor 140.

The switches 25, 011 any trace rod, muy be set in their 0fi positionwhen the traco md is in its normal position, and t0 th0 0n position whenthe trace 10d is moved t0 its f0rward osition. Nhen it is -desired t0sei a combination, assuining that all the switch members 37 0ftheswitches 25 am in their 011 position, the trac0bars con'e5ponding to thestops which are t0 be inc1uded in the combination, 2ue moved forward sothat the upwardly projecting parts 01 the sw"tch membe1s 37 are inosition t0 be depressed by the switch actuator 97. Set-fing isaccomplishecl by moving the desirecl st0p keys 10 t0 the 0n position,then depressingthe combination contro1button 128, ancl while this ishelcl d0pressed, operating the 00mbination push button 63, the latterpush button being used for the first com'bina tion to be sei. The actiontaking place is then as follows: WVhen the relay 96 is operated bypressing the combination c0ntrol button 128, the 1elay contacts 95 areclosed, which permits current t0 fl0w frorn the battery through theconductor 16, through the bridging contacts 0f the st-op keys which arein the on position, through th'e conductor 17 through conductor 94including the then closecl relay contacts 95, through the hook barlifting magnet 92 and the conductor 93 back t0 the battery. Thisenergizes the electromagnets 92 corresponcling to the stop keys in theon position, which lifts the hook bars of the corresponding tracer0c1s24. The relay 96 when operated also opens the contacts 59 and 60and c1oses the c0ntacts 59 anal 127, anc1 also the sets of contacts 134and 135. The opening of contacts 59, 60, and the closing 0'f contacts 59and 127 serves t0 remove the relay 49 froni the control 0f thecombination push butt0n 2Lnd t0 substitute ehe control of theelectr0magnet 123 0f the setting mechanism. A cifcuit is thenestablished from the battery 15 through 0011- ductor 65 to the contact64 0f the then c1ose l combination push button switch 63, from thecontact 62 0f the push button switch through conductor 61 t0 the.contact59, from the cooperating cont-act 127 through the conductor 126 130 .theelectromagnet 123, and back t0 the battery through concluctor 125.Simultaneously a circuit is establishd fr0m contact 66 of ehe pushbut-ton, through conductor 138 t0 the contacts 134, through conductor139 t0 the relay 91 and back t0 the battery through.conductor 140. The-relay 91 is' then energized, Which closes ics contacts 90 forsupplyingcurrent 60 the S016- noid 86 through conductors 88 and 89. The swingingbar 80 is moved forward by the solenoid 86 t0 effect a forward movement01 the several trace bars 24 the hook b'ars 70 01.

92. '1he,further forward moveme'nt'of ehe combmatmn push button efiectsthe engage ment 01" thecontact member 68 with the 0011- tact member 67,whichestablishes a circuit through concluctor 141, contact 135,conductor 142, re]ay 122, and conductor 143 back t0 the bat-tery. V\hen'the relziy 122 is thus energizec'l'it closes contacts 121, whichpermits currant t0 110W from thb battery "CO solenoid 117 throughcondu'ctors 119 and 120. The solenoid 117 when energized attracts fits00re 116 which eflects the forward movement 0f the swingng bar 112 andwith it0n'e 0f the hook bars 111 lifted by the electromaga net 123. Thismoves the link 109 attached to the hook bar, rocking the shafrl 107through the arm108 t0 niove theswitch actuator 27 downwardly against theupper edge of the trace bars through the' levets 106 and the links 105ab each end ofthe switch actuator. The switch actuator" 97 then moves tothe onpositi0h any ofthe switch members 37 which have beenmoved forwardwith their trace bars. O11 trace bars which have not been 1n'0vedt0their forvvard position, the switch actat0r Will move 130 ofl' positionany switch men1bers which may have been in thei1 im positi0n;

The combination control butt0n l28and the combination push button 63 arethen released and furthercombination's may be sei: in the same manner,aft0r inovingjon t he desired st0ps, b'y successively depressing:thecombination push buttons 63", 63, etc;, iri conjunction with thecomb'ingition con'tr0l push button 128, It is, of c0urse, obvious thattwo of the combination push -buttons, 01' equivalent devices,mayTespectively 0011- trol the all off 01 all 011 p0siti0n ofthe stops.

In the sequence of operations at the mechanism including the trace barsior setting t-he switch members into their desired positionm it ispreferred c0 1nove the t1ace bals bef0re moving the switeh actuator a'sabove described, but these eVents may be transposed. In the latte'l'case the switch 1ne1nbers in 21 group are first all moved to 0flt'pos'iti0n b the actu'ator, and the forward 1n0ven1en'a el selected tracerode Will then canse a rocking of the switch me1nbers thereon t0 0npositi0n by their cam action 0n the depressed actuator. v

While I have shown the s(op keys f01 securing the functioning of thestops either manually er by the mechanism this is only for the purposeof providing an indicating means, .and to permit Stops t0 be temp0rarilyincluded in 01' excluded fr0m the combination. In sorne instances, otherindicating means may be employed instead in 'which the stop keysnre1'10t moved when a combination is brought on. Since the mechanism 05 thestop actioi1 of the present invent-ion may be placed in any suitablelocation, it is possible to pro'vide any desired nurnber 0f combinationsand the console may be 1nade in standard sizes according to the number0l manuals employed, because it's size is n0t determined by the number0f combinations desiredf By suitable minor changes, it is also possibleto incorporate the mechanisrn in e'x1sting organs Olt' any type, as themechanism 0 n the Whole is me'ehariically independent of tl1e stop keys.
